o all whom 'it may concern.'

lle known that l, CHARLES H. SCAM- MELL, s citizen cl." the United States, residing et New York., county ol New York, and Stste of New Yorlr, have invented certain new end useful linproveinents in Clamping levices for Building Constructions, fully de scribed end represented in the following specification and the accompanying drow ings, forming e port ol the seine.

This invention relates tov en. improved cleinp for holding, together parte of building constructions, the especial object of the invention being to provide en improved edjustsble clump, by which the seine clamps be used for constructions varying Widely in e, end which shell provide for the cheep end convenient sssen'ibling and disasseiw bling ci the construction and shell :ivoid the loss olY time :rndperts resulting lioin the sepsrsting oi bolts, nuts, or clumps.

The clamp is applicable lor permanent perte olt buildingr constructions, but is ol' es pecielvelue and es pecisll y adapted for use in. constructing teiuliiorory cent-cringe for verticul columns, smoke stacks, piping and the like which are to be covered with concrete the clamps being used to hold the temporary centering in piece et the proper distance from the coloni-n in filling` in. the concrete. The invention will, therefore, be described in connection with clumps applied in such a. con- .1c/thm, certain lectures oli' which tempo- "y centeringr und other' temporary freine .n connection with the cleinps, forni parte ol the invention.

, tending across the centering over the bottone from clamp to cleinp, complete ties inclosing the centering being thus formed by four clumps end four bolts. Such ,s tie is Ashown et each betten, but it will be understood that only so many ties will be used es required, and that the 'battons and ties will be spaced on the column as required according to the size end character of the construction.

Referring new to the ,clamps l), each clenip consists of en angle plete hcving the two sides l0, 1], .on one of which, l0, is formed. s. lug 12 having' en open slot l. and on the other of which, 11, is e lugr 14 hevihg e bolt hole 2, and on the side ol the bolt hole toward the corner ot the clump s nut recess 3 having the nut holding shoulders 4 und end bolt stop 5. The bolts E have nuts 6 et one end and e holding head et the other, ornuts 6 et each end, and one end of each bolt passes through the bolt hole 2 of e clamp with its nut seated inthe recess 3' .and the other end of the bolt adopted to be slipped. into the open `slot l ol another clamp in erectingl the centering.

The erection and removal of the centering es shown in Figs. l and 2 will be clear from. the following` description. The four sides of the centering being formed by securing` togethcr the logging by the battons C, the sides of the centering ere put in piece, the bet/tens nailed together et the corners to hold the centering in }'ileccuntil the ties src op plied, end the successive ties Alformed by the clamps and bolts applied. The cleiups l) are letpplied et the corners with bolts ll extending from the clamps across the centering, end the lree end ci each bolt, the nut 6 on it being loosened -suliciently is slipped into the open I 40 Itjwill be seen that the invention rovides 2 v 87eme slot 1 Y01 the next clamp and the nut 6 then I held in place and prevented from crossing the tightened up against the side of thelug 12 to slot 1 by the nut or head in recess 3 and stop c amp and secure the centering.
